Pressure in Fluids - Section 8.3 Quiz

Which of the following can be expressed using the unit of force?
1. Pressure and buoyancy
2. Pressure only
3. Pressure, density and buoyancy
4. Pressure, density, buoyancy and viscosity
Which statement about pressure is false?
1. Pressure is for fluids what density is for solids
2. Pressure increases with depth
3. Gases can be compressed much more easily than liquids
4. All fluids tend to move toward areas of less pressure
What is a reason why air exerts less pressure as you go up in altitude?
1. There are fewer layers of air above you
2. Heavier particles such as oxygen decrease
3. There is less friction between air particles
4. The air is colder and therefore less viscous
What eventually happens to all weather balloons as they rise through the atmosphere?
1. They become taught and burst
2. They deflate and fall back to the ground
3. They freeze solid and fall back to the ground
4. They are ripped apart by the high altitude jet stream
What causes the pressure of a compressed gas in an aerosol can?
1. Gas particles colliding against the inside walls
2. Gas particles sliding against one another
3. Gas particles being trapped in a stationary arrangement
4. Gas particles being forced to slow their movement down
Some very unusual creatures live in an extremely high-pressure environment deep in our oceans.

The humpback anglerfish lives at a depth of 2000 m down. Researchers would like to bring one to the surface to study it but most attempts to do have failed. Why do you think that is?
1. They are adapted to very high pressure so when they reach the surface their tissues would "explode"
2. They would not able to swim in warmer surface waters
3. The pressure at the surface would crush their delicate gill structure
4. The oxygen level would be too low near the surface of the ocean for them to breathe
Temperature affects pressure. What is not an example of this phenomenon?
1. A man uses a pressure washer to clean his patio
2. A dragster spins its thick tires on the asphalt and they begin to expand
3. A balloon left outside overnight is half-deflated by morning
4. A can of beans in a campfire explodes
What is not a unit of pressure?
1. Meters per second squared
2. Pounds per square inch
3. Kilograms per centimeter squared
4. Newtons per meter squared
Which of the following would be most compressible?
1. A beach ball filled with air
2. A beach ball filled with water
3. A beach ball filled with sand
4. A beach ball filled with ice
A meteorologist on television states that a low-pressure weather system is in your area. This means that air surrounding this system is
1. rushing toward it, creating wind.
2. rising over top of it.
3. flowing away from it, creating wind.
4. sinking underneath it.
